		<xs:documentation>Geographic MetaData (GMD) extensible markup language is a component of the XML Schema Implementation of Geographic Information Metadata documented in ISO/TS 19139:2007. GMD includes all the definitions of http://www.isotc211.org/2005/gmd namespace. The root document of this namespace is the file gmd.xsd. This content.xsd schema implements the UML conceptual schema defined in ISO 19115:2003, A.2.8. It contains the implementation of the following classes: MD_FeatureCatalogueDescription, MD_CoverageDescription,
MD_ImageDescription, MD_ContentInformation, MD_RangeDimension, MD_Band, MD_CoverageContentTypeCode, MD_ImagingConditionCode.</xs:documentation>
